Abstract
An automatic document feeder is used with an office machine including a scanning module and a transparent substrate. The automatic document feeder includes a main body, an arc-shaped plate and multiple elastic pressing members. The arc-shaped plate is fixed on the main body and includes multiple protrusions and multiple openings. The protrusions are sustained against a surface of the transparent substrate to define a gap between the arc-shaped plate and the transparent substrate for allowing the paper to transport therethrough. The elastic pressing members have first ends coupled to the arc-shaped plate and have second ends partially penetrating through the corresponding openings. The elastic pressing members are arranged in a staggered form to press the object passing through the gap such that a scan zone of the object is in close contact with the transparent substrate to be scanned by the scanning line of the canning module.
